EDWIN F. GUTH, OF ST. LOUIS, MISSOURI.

SUPPORT FOB LIGHTING FIXTURES.

To all whom it may concern:

Be it known that I, EDWIN F. GUTH, a citizen of the United States, residing at St. Louis, in the city of St. Louis and State of Missouri, have invented a certain new and useful. Improvement in Supports for Lighting Fixtures, of which the following is a specification.

lily invent-ion relates to the lighting fixture art and has for its purpose to provide supporting means for a fixture which will eificiently and securely position and hold all of the parts and yet will eifectually conceal the means by, and through, which it is accomplished. A further object is to provide sucha supporting means which will positively position all of the parts with relation to each other thus establishing a definite relationship which will make possible the utilization of pull chain sockets and other desirable functioning parts which require definite established relationship with other parts.

A yet further object is to produce such a combination which will be easy and simple of assembly and of insulation.

This invention is an improvement of the invention disclosed in United States Patent No. 1,251,406 which is owned and controlled with which I am associated.

My invention consists of certain details of construction hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows a longitudinal sectional View of my improved device in connection with a junction box, and

Figure 2 shows a detail view illustrating the means I employ for fixedly positioning the socket and shell base with the canopy,

or cover. 1

Referring to the accompanying drawings the reference numeral is used to indicate a junction box, set in the side wall, or ceiling. Spanning the opening, and secured to the wall in any suitable manner, is a metal strap, or the like, 11, with a central orifice therein to permit of the passage therethrough of the electric wires (not shown). Secured also to the wall, and to the strap 11, is a forwardly projecting retaining member 12, so formed and mounted as to provide ample space between its forward portion and the strap 11 for the receiving of the socket 13. This member is, preferably, a metal strap with an enlarged portion at its I have provided an opening with one, or more, flattened, or straight, sides, 14. Obviously the strap 11 and the member 12 are immovably fixed in their positioning with the junction box and each other.

The socket is provided with a lamp receiving shell 15 which is threaded interiorly and exteriorly and an insulating member 16 also threaded interior-1y and exteriorly, is adapted to be screwed thereon, as shown. This insulating member has a base provided with flattened, or straight, sides 17, adapted o lit within the flattened or straight sides of the orifice 1 1, when the socket with the insulating member screwed to position thereon, is projected through, and seated within, the orifice 14-, the manner of doing which is obvious.

The numeral 18 indicates the canopy which is provided with a central opening to fit over the lamp receiving shell 15, the canopy covering the member 12. A threaded ring, or ferrule, 19 is adapted to screw over the insulating member 16, its inner surface engaging the canopy, and when rotated sufiiciently inwardly will firmly seat, and position, the canopy to the insulating member. This operation also firmly seats the insulating member and the socket, to the retaining member 12, thus fixedly positioning all of the parts, the inner edge of the canopy engaging the wall. A threaded shade supporting member 20 is adapted to screw over the insulating member 16 and, by means of engaging the inner surface of the shade 21, to clamp the shade against the exterior of the canopy.

It is obvious by this construction the parts of my device are firmly and securely positioned, and that all means of accomplishing the same are effectually concealed. As the parts are so firmly positioned it is possible to utilize a chain pull socket, as shown, for the taking out, or putting in, of lamps will not effect, by slightly turning, the relationship of the parts to each other, or the wall of the room.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States, is:

1. A supporting means for a lighting fixture comprising a retaining member secured to the junction box, or wall, and protruding therefrom, said member being provided with an opening with a straight side, a

forward end, and this enlarged portion socket with an insulatin member to be attached thereto and a straight side on the in sulating member to engage the straight side of the opening in the retaining member, a canopy to cover the retaining member, a shade to engage the canopy and a support for the shade to clamp it against the canopy, substantially as shown and described.

2. A support for a lighting fixture comprising a protruding member with an opening in its outer portion and a straight side to said opening, secured to the Wall, a socket with a shell screw threaded interiorly and cxteriorly protruding through said opening, an insulating member screw threaded in- 5 teriorly and exteriorly screwed on said shell and having a straight side to mate with the straight side of the aforesaid opening, a canopy and a shade and means to secure them to each other and the protruding 2 member.
